Improvement in tile-machines



STATES JOHN B. HUGHES, OF TERRE HAUTE, INDIANA.

IMPROVEMENT IN TILE-MACHINES.

Specification forming part of Letters Patent No. 116,447, dated June 27,1871.

To all whom it may concern:

Be it known that I, JOHN B. HUGHES, of Terre Haute, in the county ofVigo and State of Indiana, have invented certain new and usefulImprovements in Tile-lllachines; and I do hereby decla-re that thefollowing is a full, clear, and eX- act description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon which form a part of this specilication.

The nature of my invention consists in the construction and arrangementof a machine for Inaking tile for roofm g after having' previously beenmade into plates, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring' to the annexed drawing, in which-Figure l is a longitudinal vertical section, and Fig. Z a plan view ofmy machine.

A A represent two horizontal parallel beams, of any suitable dimensions,supported upon or forming part of a frame, B, and provided on theirouter sides with horizontal rack-bars a a. In the center, between thebeams A A, is secured the box O, ofthe same length as the tile to bemade.

In this box is laid the movable bottom D, which is covered by asheetmetal plate or pan, E. The bottom D has longitudinal depressions bb at its sides, and at one end, in the center, a square opening, d, thetwo sides of which are slightly inclined, and the inner end of saidopening is also inclined; or, in other words, the bottom D at the innerend of the opening d is hollowed out, as shown at c. The plate or pan Ecorresponds eX- actly with the shape of the bottom D, with thisexception-a small piece of metal, f, is attached to said pan under theopening d. G represents a roller iitted between the beams A A, and provided at its ends with cog-wheels hh, which rest upon and gear with therack-bars ct c. The journals of the roller G pass through a frame, H, atthe lower end of which are friction-rollers t' t', bearing against theunder sides of the beams A A, thus steadying the frame or carriage H,and at the same time allowing it to move back and forth on the beams.The ends of the roller G,

immediately inside of the cog-wheels h h., are grooved circumferentiallythe width of the beams A A, so that the main portion of the ,roller titsy between the beams, the grooves on the beams, and the cog-wheels on therack-bars. At a suitable point on the roller G is a longitudinal rib, k,i having in its center a projection, m, corresponding with the opening dand bevel c of the bottom D and pan E. I is a crank attached to one ofthe journals of the roller G, outside ofthe frame or carriage H. 'Underthe box O is a follower, K, with four upright rods, n n, passing throughholes in the bottom of said box. This follower is raised by afoot-lever, L, so as to lift, by the rods a u, the bottom D and pan E upfrom the box a suitable distance. The sheets or plates for the tilehaving been made by another machine, (for which I have made a separateapplication for Letters Patent,) are laid on the pan E. Then, `by thecrank I, the rollerl moved over the same, rolling the sheet, thedepressions b b formingribs along the edges of the tiles. The rib loforms a shoulder of reduced thickness at one end of the tile, and theprojection -m forms a groove on one side with corresponding rise in theother, and a bevel or hollowing out at the inner end of said groove. Theconstruction of this tile and the object of these ribs, groove, &c., arefully set forth in an application of mine for patent on roofing, nowpending. When the roller G has passed beyond the box, the bottom D, witheverything upon it, is raised by the foot-lever L, the pan E with thetile removed, and taken to place ot'burning, where it is turned upsidedown and the pan taken off. 1

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The movable bottom D with longitudinal depressions b b, opening d,and bevel c, substantially as and for the purposes herein set forth.

2. In combination with the movable bottom D t. constructed as described,the pan E, having corresponding shape, substantially as and for thepurposes herein set forth.

8. The combination of the beams A A, rackbars d a, box O, bottom D, andpan E, all constructed and arranged substantially as and for thepurposes herein set forth.

4. The combination of the roller G, frame H, crank I, friction-rollersit', and cog-wheels h h, all constructed and arranged substantially asand for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
